Consequently the two telescopic tubes l is the inner and 2 the outer telescopic tube. can be turned with respect to one another through The tube I has a pressed-in longitudinal groove an angle which corresponds to the width of the 50 3 in which the tube 2 is guided by means of a slot and is about 45. The button l9 does not projection 4 which is made by the material being hinder this rotary motion, as it is only about as pressed out inwards. The extending is limited by high as corresponds to the wall thickness of the an arrangement to be described hereinafter. On two tubes. As will be seen from Fig. 6, only the the telescopic tube Li a sleeve-like sliding memcalotte of the button l9 projects slightly beyond 55 the corresponding hole of the outer telescopic tube, so that only slight resistance is offered to a turning motion.

In order to open the umbrella, the telescopic stick and rib parts must first be extended. This is effected-by holding the umbrella point or tip with one hand and the umbrella handle with the other hand and then exerting a pull with both hands in opposite directions. The extending motion is limited in such a manner that the projection 4 of the outer tube 2, which is guided in the groove 3, bears against the button 20 of the U-shaped spring I8 of the inner tube 1 (Fig. 6) and the button [9 of the spring [8 enters a corresponding hole of the outer tube 2. In this extended position of the umbrella frame, the projection 4 of the tube 2 is next to the excision 2| of the tube l and the projection ll of the parts 12 are next to the corresponding excisions l6 of the parts I3 so that a locking can take place by a relative turning of the parts. If the umbrella handle 22, which is only axially displaceable on the telescopic tube, and the umbrella point or tip are turned in the direction of the arrow according to Figure 4, the spring catch 8 of the tube 2 lying in the corresponding excision of the sliding member 5, the projection 4 will be locked in the excision 2| and the projections I! will be locked in the excisions [6 because the rotary motion is transmitted from the sliding member over the Spreaders I to the sleeves I4 and the outer rib parts I3 connected therewith. During the turning motion, the calotte-shaped button l9 passes out of its hole in the outer tube. The U-shaped spring presses it against the inner Wall of the outer tube I so that the telescopic parts are held in the locked position by friction.

The umbrella may be folded like an ordinary umbrella.

For holding the free ends of the outer rib parts in the telescoped position the following arrangement is provided.

The umbrella handle 22 is formed like a bell, the rim 23 of which is at such a distance from the umbrella stick that the free ends of the outer rib parts l3 can enter the cavity. A sleeve 24, to which the umbrella handle is fixed, is slidable on the outer telescopic tube 2 and is secured against rotation with respect to the latter through a pin 25 which is riveted at one end and is slidable in a slot 26 of the outer telescopic tube. The length of the slot determines the distance through which the handle can be slid. For preventing un' intentional movement of the umbrella handle a substantially U-shaped leaf spring 21 is slid over the pin, the limbs of which are fixed at 28 to the outer telescopic tube. The middle part of the leaf spring is compressed to an extent corresponding to the length of the slot 26. From Figs. and 11 the position of the pin 25 with respect to the leaf spring in the two extreme positions will be seen.

For facilitating the assemblage of the telescopic tubes holes 29, 30 (Fig. '7) are bored above and below the projection 4, for enabling a fork-shaped tool to be inserted, which presses the button 20 in to such an extent that, on the outer telescopic tube being slid over, the projection 4 will pass over it.

The constructional form illustrated and described is only a constructional example. Many modifications are possible within the scope of the invention. More particularly it is possible to arrange the parts oppositely to the manner shown.
